The mounting and configuration of the abrasive particles, and such methods require little or no post-electrodeposition of the tool working surface. In other words, the working surface is produced by the electrodeposition procedure (4). Applicants have also developed molds for this manufacturing process and developed a number of abrasive tools produced by the manufacturing process. Please refer to the figures -A to -e, which show a mold of the present invention. The mold 10 can be made to determine the number of the plurality of drills η = 固 固 (4) The mold surface of the mold 1G, please refer to the first Μ - Η diagram, which is shown in an embodiment of the present invention, The structure of the mold used in an electrodeposition chamber (10) is 10 kg. Similarly, the second to second c-pictures show other examples of the structure presented by the mold ι in an embodiment of the present invention.

As shown in the figures, the mold 1〇 contains an insulating material crucible. This insulating material 14 can effectively prevent the electrodeposition material (Eleetr〇 deposited material from accumulating on the molding surface 18. In the examples shown in the __f to the first h-th and the _A to c-c drawings, The tip end 42 of the abrasive particle 22 is formed as part of the working surface 49 of a tool 5', and 'the tip 42 is fixed to the molding surface during electrodeposition, and the "Hai/Nuhe material 58 can be Avoid accumulating on the working surface 49 of the abrasive particle U-tip 42 and the tool 5〇.

Please refer to the first a to In the first embodiment, in another embodiment, the insulating material 14 has a plurality of holes penetrating the insulating material η, and the same holes 26. The holes 26 are provided for the electrolyte 30 from the mold 1〇11 200800504 The outer region 3 4 loops from #, A yg , the clothing teeth through the cookware 10 to the tool substrate 54 " to effectively electrodeposit the abrasive particles 22 to secure the tool substrate 54 The material above. Because of this cycle, the electrolyte is maintained at the electrodeposition. (FIG go): poor 0, k S does not) / e of the piece goods to be, so the cycle is advantageous. In the examples of the -G, the first G, the second B, and the second C, the electrodeposition is on the surface % of the tool substrate 54.

In a detailed example, the plurality of holes 26 can be configured in accordance with a predetermined pattern. For example, t, the preset graphic may be a - lattice, such as -A and -d (d). The lattice pattern helps to uniformly distribute the ions of the electrolyte 3〇 to the substrate 54_h. The uniform ion distribution helps to uniformly build the electrodeposited material 58 over the surface of the tool substrate M, thus helping to fix the abrasive particles with uniform strength. In other embodiments, the plurality of holes 26 can be configured to cause more electrodeposition in a particular area. For example, Figure 2B shows the holes 26 in the plurality of recesses of the mold. There are more electrolyte ions near the hole 26 to cause more electrodeposited material 58 to be formed there. The insulating material 14 can be formed in a variety of ways. In an embodiment, the material 14 can be formed from a resin. For example, the resin material may be an artificial resin or a polymeric material such as Polyimide. The resin material may also contain epoxides (Epoxies), lacquers (Lacquers), varnishes (Vanishes), and mixtures thereof. In addition, the resin material may be a rubber material and comprises natural and synthetic rubber, such as Styrene-Butadiene, Polychloroprene Elastomers, Polyuroprene Elastomers, Fluoroelastomers, Ethylene.

The insulating material 14 can also include a molding surface 18 that is electrolytically deposited by an electrodeposited material 58 to solidify the abrasive particles u to a surface of a conductive substrate 54 (eg, tool substrate 54). When used, it is used to fix the abrasive particles + 22. The mold 1σ can fix the abrasive particles 22 such as diamond particles or the like in various ways. For example, in the molding table (4), an adhesive material 38 may be adhered to fix the abrasive particles 22. The adhesive = 38 can be used to independently arrange the individual abrasive particles η. Other methods of solidifying the abrasive particles 22 may include magnetic force, friction, gravity, and the like. For example, the abrasive grains...n may include a plurality of grooves for the purpose of the "sandwich" fixed in the groove. Please refer to the first E map, in a 杳#7丨山..π in κ In the yoke example, the abrasive particles 22 are fixed so that the shape of the direct contact molding surface can be controlled - for the second 8 having a "ground" configuration, the next day, the vertical pattern 6 of the tool 50 2. 0月荟, 3⁄4弟二A to 箆-r罔 blood, a picture, for example, the molded surface can be assigned 13 200800504 to have a shape with a vertical figure (four) inverted to correspond to a tool base Abrasive particles on the material 54. The shape of the molding surface 18 itself may be suitable for many applications of the abrasive tool 5. For example, the molding surface may be substantially flat (as shown in Figures A through G), The concave or convex shape or the molding surface may include a plurality of concave portions and convex portions (such as the second A and second B patterns). Another example that is particularly useful for chemical mechanical polishing (CMp). The recess of the molding surface may have a slope of about i/i 或是 or about 1 Concavity of /1000. In this last example, the vertical pattern 62 of a polishing tool can have a convex shape with a slope of about 1/1000, which is a condition generally required for CMp applications. Moreover, in some K yoke examples in which the abrasive particles 22 are in direct contact with the molding surface 18, the abrasive particle tip '42 forming part of a tool working surface 49 can be provided in accordance with a predetermined vertical pattern. And good finish quality... This allows for being thrown: the object has a special configuration pattern. In some embodiments, the abrasive particles 22 can be attached to the molding surface 18 in accordance with a predetermined horizontal pattern. The spacing between the abrasive particles on the surface of the tool substrate 5 5 can be controlled. Such control can have some benefits. For example, the controlled spacing of the abrasive particles can reduce excessive friction (or drag). And reducing the heat cycle b produced to increase performance. In some embodiments, the abrasive particles must be regularly distributed on the surface of the tool. To achieve such applications, the abrasive particles Fixing on the molding surface according to a lattice pattern. 14 200800504 The abrasive particles can be positioned on the molding surface according to a predetermined horizontal pattern by various techniques. For example, the abrasive particles can be individually set. On the molding surface. Alternatively, the same plate (as defined above) can be used to more effectively place the abrasive particles on the molding surface. Other methods can use a transfer belt or other transfer medium, and the abrasive particles are based on A predetermined horizontal pattern is temporarily disposed on the transfer belt and then transferred onto the molding surface. In an embodiment of the invention, the abrasive particles 22 may be preset according to a pattern complementary to the hole 26 A graphic is attached to the molding surface 18. For example, the abrasive particles and the holes can be configured according to respective lattice patterns as shown in Fig. 1D, respectively. Advantageously, the &complementary pattern allows electrolyte 30 to be electrodeposited around each abrasive particle at substantially equal ion concentrations. Therefore, the amounts of the electrodeposition materials 58 that respectively fix the respective abrasive particles are substantially equal. This helps to maximize the retention of the abrasive particles by distributing substantially equal working loads onto each of the abrasive particles. In other embodiments, the abrasive particles 22 can be attached to the molding surface 18 ± according to a pattern that causes the abrasive particles on the at least one specific region of the molding surface to have a higher density of distribution and higher than the molding surface. Abrasive grains in the rest of the area? Distribution density. This graphic is especially useful in CMP applications. For example, it is possible to have a higher abrasive particle distribution density on the periphery of a disc-shaped abrasive tool. The disc-shaped grinding tool has a peripheral rotation speed higher than that of the core, and there is a large pressure at the tip end of the #-shaped tool. Applicant's US Patent No. 1/1〇9,531, Patent No. 15 200800504, filed on March 27, 2002, and U.S. Patent No. 10/954,956, filed on September 29, 2004 by the two main λλ, 'd days Other abrasive particle patterns and configurations are disclosed in the application, which are incorporated herein by reference. In another aspect of the invention, an alternative method is used for manufacturing a grinding tool 50, wherein the abrasive material is bonded to a plurality of abrasive particles 22 through an electrodeposited material 58. - on the substrate 54. In an initial step, the plurality of abrasive particles can be temporarily secured to the molding surface 18 of the cookware 10 as described herein. Next, the read 杈 cookware and the broken abrasive particles can be placed in an electrodeposition chamber 1 with the surface of the 杈 4 facing the substrate. Next, the material is electrodeposited on the surface 56 of the substrate 54, and abrasive particles such as wires are electrolytically attached to the substrate through the electrodeposited material. The mold can be removed to expose an entire or vertical, ΒϊA-Jade 1 knife grinding tool, which in turn encloses the substrate and the abrasive particles attached to the surface of the substrate. In one example, the abrasive 4 abrasive particles 22 are affixed to the mold and through the coated surface 18 of the mold through a bonding material 38 as described above. Through the facing material, until the grinding heart 4 58 can be formed on the base and a part of the general uncle is covered. The electrode sink is capable of reinforcing the abrasive particles more firmly, and the material is fixedly attached to the adhesive material, and therefore, the mold can be easily removed to expose the catastrophic end of the abrasive particles. In the only embodiment, the substrate 54 can be a conductive material such as a non-ferrous steel. The substrate itself acts as a tool body (not shown). The substrate may not be fixed to a body by a method later: In the other embodiment, the electrodeposition (4) 58 may be - gold V ... for example - a metal or a metal constituent material. For example, the electricity 16 200800504: the material may be a metal such as nickel, chromium, copper, titanium, tungsten, tin, iron, silver, gold, short, magnesium, zinc, aluminum, a button, an alloy thereof or a mixture thereof . The metal constituent material may be a composition comprising at least one of the above metals. In another aspect of the invention, an abrasive tool 50 made by the above method is provided. The abrasive tool includes a substrate 54 to which a plurality of abrasive particles 22 are bonded by electrodeposition material 58. The grinding, sub-tips 42 can be configured in accordance with a predetermined vertical pattern. In addition,

A part of the abrasive particles such as Hai may be exposed to the electrodeposited material without being covered by the electrodeposited material. * For example, the abrasive particles 22 can be set to a uniform height or substantially equal height that protrudes from the substrate. The vertical pattern may also be concave or have a plurality of convex regions and concave regions. In addition, the abrasive particles 22 such as ^hai can be attached to the base material according to a predetermined horizontal pattern. For example, f, the abrasive particles can be based on one of the above enthalpy. Configurable. The abrasive particles can be configured to have a higher density of distribution of a particular article or abrasive particles on the substrate and a higher density of abrasive particles than the rest of the substrate. These vertical and horizontal patterns have many of the advantages described above. In other embodiments of the present invention, an abrasive tool 50 can only require a pole and does not require a post-electrodeposition procedure of the working surface of the tool. In this embodiment, the electrodeposited material 58 is formed on the substrate 54 of the tool, and does not form on the finished surface 49 after the tool's table Φ 49 has been completed. Therefore, the finished work surface does not need to be processed to expose the tip 42 of the abrasive particles as it is. 17 200800504 This helps to avoid damage to the abrasive particles due to the impact of refurbishing the working surface of the abrasive tool. EXAMPLES In order to make the present invention more understandable, several examples will be provided below. However, such examples are not intended to limit the scope of the invention. Example 1 : CMP Dresser (CMP Pad Dresser)

A mold having a polyimide layer (lmm thickness) is embossed to have a plurality of holes arranged in accordance with a lattice pattern. The center of each hole has a pitch of 〇.7 mm in the other holes, and each hole has a diameter of 〇. A surface of the polyamidamine layer (for example, a molding surface) is coated with an acrylic (polymer) adhesive (5 〇 〇 〇 厚度 thickness) ^ is attached to the molding surface with a plurality of 〇〇 /12〇Mesh diamond abrasive grains Each diamond abrasive grain system is located at the center of four adjacent holes. The molded surface covered by the diamond was placed adjacent to a disk-shaped stainless steel substrate (having a diameter of 108 mm and a thickness of 65 faces). The diamond abrasive particles are located between the molding surface and the substrate. The mold and substrate are located in a plastic (PVC) ring 48 to hold the mold and substrate together during the electrolysis process. The substrate is in contact with a cathode. The electrolyte is a sulfide recording solution. The plastic ring, the mold and the substrate are impregnated with an electrolyte located in the -PVC reed, and the PVC layer is used to seal the electrolyte. The electrolysis was carried out on a 4 substrate in a 7 Å table. The electrolysis continued until the size of the diamond abrasive grain covering the near = about flat = 2^3 was recorded. The polyamidamine mold is then transferred to obtain the substrate through which the permeation flux is attached to the nickel and the diamond abrasive particles are attached. 18 200800504 Example 2 Thirty molds were fabricated as follows: The master mold was formed from a stainless steel disk having a diameter of about 120 mm and a thickness of about 120 micron. Each of the disk systems is etched by a lithographic pattern to form a plurality of holes which are arranged in accordance with a lattice pattern as described below. The holes are distributed in a circular area having a diameter of about 10 mm at the center of each disk, and the rest is adjacent to the circumference of the disk and having an area of about 20 mm in width. Has holes. The spacing between the approximate center points between adjacent holes (i.e., the hole spacing) is measured. Some of the disks have the following hole spacings. · Ten disks have a hole spacing of about 800 micron, and each hole is directly controlled by about 400 mircori. 2. Ten discs have a hole spacing of approximately 6 〇〇 micron, each hole being directly controlled by approximately 300 mircon. ^—3·10 The hole spacing of approximately 400 micron, each hole _ hole diameter is approximately 200 mircon. The mother disc is coated with varnish, rubber or coated with an inert material or an insulating material to enhance its electrical insulating properties. However, in some applications the mold itself is a low conductivity or non-conductive material, so the coating step described above can be used as an optional step. In some instances, when the abrasive particles are insulated (e.g., diamond particles), the stainless steel disk or other conductive disk is isolated from the cathode substrate by intervening abrasive particles to thereby insulate the disk. By using the mold described above, the following procedure can be used to make a diamond 19 200800504 Diamond Pad Conditioner: 1. Apply an adhesive layer on both sides of each mold, and assemble the abrasive particles on each side. Template. The abrasive particle templates are configured and selected to properly accommodate abrasive particles having a predetermined size and allow the abrasive particles to adhere between the holes of the mold of the corresponding template (in other words, the holes in each of the templates are configured Compensate with the holes in the mold to ensure that the abrasive particles will adhere to the mold surface ± without A falling into the hole through the mold ^). 2. The mold and the template assembly are threaded with at least one bond A corresponding bonding hole formed in each of the components in the assembly to fix the group 2. However, it should be noted that other mechanisms, such as clamps, adhesives, etc., may also be used in conjunction with the molds and templates in the assembly. , a 3_ diamond particles of appropriate size (Diam〇nd Inn〇vati〇n 5 kg clothing MBG-660) are placed in the holes of the sample to make each dragon table (four) abrasive particles ▲ sub. ~ ---------- 4.

A heavy steel ring is pressed around the outer periphery of each mold to ensure that the mold does not move, translate or deform during the electrodeposition process. In some aspects, the heavy steel ring can actually bend the circumference of the mold slightly to form a recess on each side of the mold. The hypotenuse of the recess can be slightly controlled by this mechanism. In some aspects, the slope can be about 1/1 〇 (9). This allows the diamond particles on the working surface of the substrate to be slightly below (about 5 〇 〇 〇 〇 )) the center of the substrate in the finished tool. 8 • Place each mold/substrate assembly in a plastic holder. The base of the substrates is attached to the cathode of a plating bath. The mold/base components are covered by a nickel sulfide electrolytic solution (i.e., disposed in an electrolyte bath or cylinder), and when the substrate is energized, nickel ions are reduced and nickel metal is deposited on the «base substrate. When a nickel layer is formed on the substrate, the nickel layer grows toward the mold, and the abrasive particles attached to the mold are eventually covered by the nickel layer and selected in the nickel layer. The abrasive particles can be controlled by the operator of the program. In one aspect, the depth of the nickel layer can be about i/2 to 2/3 of the distance between the substrates. Since the electrolytic solution can flow through the perforations of the mold cyclically, the nickel layer can be formed uniformly and rapidly. 9. The mold cannot be over-charged due to the intervening insulating diamond particles and the selected varnish coating or other insulating material, so nickel will not deposit on the mold or the diamond particles on the near-nuclear surface. 10 - Once the nickel layer is formed, the abrasive tool and the mold are removed from the electric dream solution and separated from each other to expose the molding surface of the abrasive tool. 21 200800504 The mold is reusable. Since the nickel layer grows from the substrate to the mold, and the abrasive particles are attached to the substrate due to the growth process, the longitudinal appearance of the exposed diamond particle tip on the finished tool is finally affected by the shape of the mold molding surface. influences. In this manner, the diamond particle tips can be configured in accordance with a predetermined vertical pattern on the working surface of the finished final tool. In addition, due to the nature of the program, the finished grinding tool does not need to be assembled through the post-assembly Φ private sequence or work 70%. In other words, in some aspects, once the nickel layer is formed and the abrasive tool is removed from the plating bath, a ready-to-use abrasive tool product has been completed. Of course, the reader should be aware that the above examples are merely illustrative of the application of the principles of the present invention. Without departing from the scope and spirit of the invention, those skilled in the art can make various modifications and different configurations, and the scope of the appended patent application is intended to cover such modifications and differences.
